Barnes XPB 225gn 45Colt load

[338 Imperial]

Looking for extra load data for +p loads for the Barnes 225gn in a 45Colt.
These will only be shot in a lever gun & an OLD Vaquaro so the higher pressures will be safe.
Barnes only lists 2 loads, w/#9 & Enforcer powders .
What have you had success with ?
thx Ed

All the usual warnings apply here. Winchester 92 and 94 action ; Whats safe in my guns etc etc . Now it don't meter worth a darn but 13.0 gr of 800X will move with speed authority and accuracy.
Ken Waters liked it to.
